 ### Changed
 
 - Docker: Explicit `init` is no longer required in Docker Compose. It is now built into the image.
+- Reduced size of the `recyclarr` executable
+- macOS & linux are now released as `tar.xz` archives instead of `zip`.
+
+### Fixed
+
+- Fix CoreCLR / "killed" crash on Apple macOS platforms (#39). This was accomplished by properly
+  signing and notarizing Recyclarr.
